Genoa sheet carrs position?

[benw]

Having experimented in light medium and heavy airs with the genoa track carrs can any one offer the definitive? We have an overlap[ping furling genoa which is a pig when furled to set. I know this is one of the drawbacks of the furling genoa however feel i should still be able to get best advantage tweaking the carrs.
I believe it should be fwd for light and aft for heavy. I stand back for the barrage of advice...
Many thanks,
Ben

I've never heard that rule of thumb before.

To get something that isn't just spouting, "Illustrated Sail & Rig Tuning" gives the following:

*Start with the car such that the Genoa sheet points at the mid point of the luff
*Then try getting the sail to luff
*If the top luffs first, move the car forwards
*If the bottom luffs first, move the car backwards
*If it luffs along the whole length at the same time, you are doing it right

In heavy airs you usually want a flatter sail (assuming you are beating), but you would control that with Genoa sheet not with the car.

That's what I try to do, it's based on that book, so if it's wrong then I'm doing it wrong

I have read (and put into practice) the advice that you move the cars forward in lighter airs - to give the sail a fuller shape. Bringing the cars back flattens the sail (tightens the foot rather than the leech). When partly furled the cars need to go forward too.

Buy the book...

There are two that are worth their weight in gold imho:

Illustrated Sail & Rig Tuning by Ivar Dedekam
SailTrim - NorthU

The first is small enough to use in the cockpit and the second is a bit more heavyweight but still pretty accessible.

Buy, read, digest, practice. They are very good.

Cheers,

My understanding (and practice) is just as Marmalade has it.

Having bought a new 130% genoa with a padded luff I can report that poor sail shape when partly furled is a thing of the past.

Flying Penguin has it right.Thats what I do.If it is really blowing you can have your cars back a bit.This will open the leach a and spill the wind.

It seems to me that everybody is saying the same thing as the OP originally proposed?

Yes, but only as a secondary effect/method.
